Re: [TRNSYS-users] Previous value of equation



Ismail,

  If you have the TESS Controls library you can use Type660. If you do not then you can use Type93 in the standard library.

kind regards,

 David

Dear Tnsys users,

I would like to know how to insert the previous value in an equation depending on time. For example to program the following equation : RH(i) = RH(i-1) * Constant; where RH is Relative Humidity of a zone. How to program the RH(i-1) in the equation block ?

Thanks in advance.
Best,
Ismail
